wrapping gum, chocolate, and the like, and

has for its object the mechanical application of two wrappers, one of paraffined paper and the other of ordinary paper bearing-advertising or other printed matter.

The invention consists in a variety of .novel features, details, and combinations hereinafter set out, whereby a simple,.strong, and

The machine about to be-described is primarily designedfor wrapping gum and chocolatein the form of cakes, though it may lie used .for putting up merchandise of various kinds .when brought to the proper form and dimensions or if the machine be made or adjusted to suit; As the construction and the machine,

.- chine will mode of operation will remain the same for any class of goods that may be handled by scription by saying that two wrappers are used, the inner one being in the present instance of paraffined paper passed about the goods and the other a printed wrapper passed about the same at right angles to the first and serving to bind in or hold in place the infolded 'ends of the first wrapper.

while paraflined paper is here employed as one of the wrappers, this is in no sense essenanother, the strips 12.

tial, each wrapper being of such character as the circumstances of any given case demand or suggest. Thus one wrapper may be of paper and another of metal foil, or both may be of foil, or other material or combinations of material may be adopted.

Referring again to the drawings, the mabe described detail. As best shown in Fig. 1, where the machine is seen in perspective, it has a base-plate or bed I raised to a convenient height above its table or support 2 by short legs or feet 3, which are preferably screwed or otherwise made fast to the table or support to give steadiness to the mac ne and prevent it from being lifted or moved bylthe driving-belt.

ble 5 and between it and venient to make use parafiined paper, but to cut the outer wrapare'shown in Figs. 1,

From the baseplate or bed 1 rise two vertical plates or standards 4 4, which serve to support an upper bed or table 5, uponand above which are arranged most of the ,operative devices. by which the wrapping operations are effected. Beneath the upper tathe bed or baseshaft 6, carrying plate 1 extendsa horizontal which the wrapa series of rotary cams by ping devices are actuated ments are timed.

It is to be observed that all the operative I gum, chocolate, or goods parts of the wrapping mechanism, including the feeding, cutting, pasting, folding, pressing, and ejecting devices, receive their power and motion from rotary cams carried by a single strai ht-line shaft, thus reducing to a minimum t e power required-for operating the machine, permittinga-high rate of speed,

preventing vibration or jar, and reducing the driving mechanism to a very simple form, while insuring and maintaining perfect timing of the parts. The principal devices involved in cutting, applying, and foldingthe wrappers are located upon the table 5, and the levers by which power and motion are transmitted to them from the cams reach upward through openings in the table.

The paper of which the wrappers are made may be cut to size and fed in piece by piece or cut from strips of a length sufiicient to produce a limited number of blanks, or they may be cut from a strip of great length wound upon a reel. In practice I find it conof a long strip of. the

I shall simply preface the le-.

lengthwise I and their moveper from a strip of moderate length or to have them wholly separated before supplying then-rte the machine. I shall here describe the outer wrapper as cut from a strip comprising about a dozen or'fifteen wrappers, it being found convenient to print the strips in this length.

In Fig. 1 I have shown a reel 7, carried by an axle 8, adjustably clamped or secured in a slotted post 9 and serving to carry the strip 10, from which are cut the inner-wrapper blanks, and I have further shown a trough or guideway 1.1, in which are placed, one after The two strips extend lengthwise of the machine and parallel to ward and subjected to the action of cutters which sever the blanks. The blanks are laid one upon the other, and the gum or other merchandise is laid upon them, after which the blanks are folded about the gum and secured.

The relative positions and arrangement of the wrapper-strips will be readily understood upon reference to Figs. 1 and 2, which show also the gum-magazine 13 and the feeding and cutting devices.

T he gummagaztne.The magazine 13 consists of a series of parallel vertical rods or wires, (six being shown in the lower ends-of which are screwed or otherwise secured in a block or the front of the table 5 and just. above the level thereof, their upper ends being connected and held in proper position by a frame 15. The frame 15 is open at the forward side to afford ready access to the goods contained in the magazine and to permit them to be loosened or straightened in the rawings,) the I base-piece 14, located at event of their becoming jammed or lodged.

The devices forfeedin or delivering the W111 be explained after pointing out the mode of feeding the wrap er-strips, severing the blanks therefrom, an placing the two blanks one upon the other in position to receive the goods.

Outer wrapper.The strip 12, from which are cut the outer wrappers, is laid in the I trough-like guide 11, F 1g. 1, and its forward end is advanced until it comes even with the blade 16 of the cutter, by which the blanks are severed from the strip, said cutter being seen in Figs. 5, 8, and 9. The cutting device as a whole will be described in its appropriate 1 place. As one blank after another is severed the blade serves as a stopor gage for the strip, determining the point from which it will be drawn forward, and as the advance is effected by nippers having a prescribed and unvarying range of travel 1t is apparent that all blanks severed will be of precisely the same size. Th'

Outer-wrapper mpperae ni ersb which the outer-wrapper blank is aggancefl 2, and 3 and on a larger mm the magazine scale in Figs. 8, 9, 10, and 11, Figs. 8 and 9 showing also the construction of the cutter and its relation to the nippers. Fig. 9 shows the cutter inits elevated position, with the parts in the positions the occu y when the lade has just severed a lank om a strip previously carried past the cutter.

The nippers A comprise two members 17 and 18, the member 17 bein a rigid member made integral with or suita, ly secured to a slide 19 and the member 18 being a lever of the first order, pivoted or fulcrumed upon the fixed member 17. The forward ends or jaws of the members 17 and 18 are broadened out to form fiat plate-like grip ing-surfaces, as seen in Figs. and 11, so t at they may gras the wrapper-strip firmly, but without liabi ity of cutting, tearing, or buckling the same in the act of drawing it forward.

The rear arm of the lever or member 18, which extends a considerable distance from the fulcrum or pivot, has its extremity beveled, as shown in Figs. 8, 9, 10, and 11, to enable it to ride down in front of and to force back a hook or catch 20, pivoted upon the slide 19 and drawn toward the end of member 18 by a spring 21. The urpose of the hook or catch 20 is to hold t e jaws of the pincers in their closed or grip ing relation, as illustrated in Figs. 8, 9, and 10, to prevent accidental OT'VEIGIIHWUIG release of the wrapper-strip. en the nip ers go forward to seize the wrapper-strip, t e jaw of member 18 is separated slightly from jaw or nfimber 17, as seen in Fig. 11, to permit the strip to enter readily between them. This separa- ..tion may be effected by a spring or by ravity, the jaw end of the member 18 eing made enough heavier than the other end to secure proper opening. At the moment that the ni pers advance to seize the wrap erstri t e cutter-blade 16 is withdrawn be ow the evel of the bed or table 5, leaving the end of said strip, which protrudes beyond the end a of the trough or guide 11 a short distance, free to be reached and seized by the nippers. After the open nippers advance to the osition indicated in ig. 8, where their aws pass, respectively, above and below the proecting end of the wrapper-strip 12, they are closed upon the strip by the overhanging horizontal arm of, an elbow-lever 22, Figs. 1,

2, 8, and 10. Lever 22 is fulcrumed upon a standard 23, secured to the bed or table 5 in such position as to'cause the lever to overhang the rear end of member 18 of the nippers when the latter are at the extreme of their advance or forward travel. It is found advisable to form a raised stud 18 upon the lever or member 18 for the lever 22 to bear upon; but this is not essential. I

The mechanism for actuating the elbowlever 22 is illustrated in Figs. 8 and 10 and comprises a pendulous lever 24, fulcrumed to a block or stud on the under side of table or bed 5 and connected by a link 25 to the lower end of the vertical arm of lever 22, the lower extremity of pendulous lever 24 being arranged in the path of a stud or block 26, carried upon'the periphery of a wheel or disk 27, mounted upon the main shaft 6, as seen in Figs. 8 and 10. Under the arrangement shown all parts of the ap aratus operate once 7 in each revolution of t e main shaft, and there is consequently one block 26 on the eri hery of the wheel; but obviously it may be uplicated if the other parts be made to repeat their operations in a single revolution, as may of course be done by properly shaping the actuating-cams. The wrapper-strip 12 being seized by the nipper-j awe and said aws being locked by the hook 20, engaging lever 18, the slide 19, upon which the nippers are mounted, is moved outwardor away from the cutter-blade 16 a distance exactly equal to the length or measurement of the blank required to produce the outer wrapper. This movement is eflected by a lever 28, fulcrumed at its lower end to a block or lug 29 on the base-plate 1 and provided with a stud or bowl 30, which enters the peripheral cam groove of a cam-wheel 31, the up er end of the lever being connected with ide 19 by a link 32, as seen in Figs. 8 and 9. Camwheel 31 is carried upon shaft 6.

Outer-10m, per-nipper release.-It is desirable to checl r the outward throw of the slide 19 and its ni pers, and it is of course neces-g sary to with aw the'hook-or catch 20 in order to permit the nipper-jaws to separate and to release the wrapper-strip 12. o accomplish this double purpose, I provide what I term the hi per-release or trip, which is illustrated in Figs. 1, 2, 11, and 11 This device comprises two levers 33 and 34, independentl lcrumedupon the upper table or ed -5 si e by side, as shown in theseveral figures, and a spring 35, tending to swing the lever 34 about its pivot-in the direction of travel of the hands of a clock. Lever 33 lies flat upon and close to the table 5, with-one I end overhan g the runway of the nipperslide 19 and Tying in the path of the lugs in which the hook 20 is pivoted, so that as said slide moves outward it shall engage the nose of said lever. Lever 34 has but one arm in plane with lever 33, and a second arm raised to-a higher plane to pass above the lugs in which hook 20 is pivoted, as shown in Fi 11 and by dotted lines in Fig. 9. Both en s. of lever 33 and the end of the raised arm of lever 34 are fashioned into rounded bearing points or noses, which project laterally from
